Water Softener Resin Buyers Guide
What is Water Softener Resin?
It doesn’t matter if you have private well water or water from a municipal supply; you’ll likely experience issues with hardness in your water. These hard minerals are typically ions, including aluminum, calcium, copper, iron, magnesium, manganese, zinc, and more.
Even though it isn’t a health hazard, hardness in your water causes many other issues. For example, your home’s appliances, pipes, and plumbing fixtures could experience damage from these minerals in your water.
Many homeowners solve this problem by using water softeners. The most popular water softeners are salt-based units featuring a resin bed. Water softener systems use resin beads to facilitate the exchange of ions and remove excess minerals from your water. That means, the resin inside your water softener removes calcium and magnesium as water flows through. Replacement resin creates a positive charge for hard minerals and leaves you with softer water.
How Does It Work
Water softeners are an ideal solution when you want to remove all excess minerals and other substances in your home’s water. Water softeners work by using an ion-exchange process. Depending on the model you select, these systems typically feature a mineral tank or one or two brine tanks.
In the mineral tank, you’ll find a medium called resin. That resin contains beads of varying sizes depending on its manufacturer. These beads contain sodium ions and have an opposite electrical charge. Those features are what attract the hard minerals in your water.
When water passes through the resin beads, the various charges react with what is in your water. As a result, the minerals stick to the beads and effectively remove them from your water. Throughout this process, you end up with soft water.
When the resin bed is no longer sufficient, it automatically goes through a regeneration process. Some also refer to this as the brining process. During this process, a salt-brine washes and flushes away any hard substances that might remain in the resin bed.
Different Types of Resin
Choosing the right type of resin medium involves what’s available and understanding their differences. There are currently only two types of resin, but, despite that, you might find it challenging figuring out which type of resin medium to choose. In this section, we outline both to help you figure out which type of resin is best for your home.
Fine mesh resin
Fine mesh resin works by using small resin beds to eliminate hard minerals up to ten parts per million. You’ll experience the best results if you combine fine mesh resin with activated carbon. That way, you can improve the feels, smell, and taste of your water.
Standard ion exchange
This process is typical for most of the industry’s water softeners. You’ll find that most water softeners come in two types–8% crosslinked and 10% crosslink resin. These water softener resins can remove hard minerals that are between three and five parts per million. These water softener resins typically use chlorine or sodium to recover during the regeneration process.
What Does Crosslink Mean?
When you see the term crosslink or cross-linked, that’s the measurement of the amount of divinylbenzene (DVB) that’s in the resin’s formulation. Because polystyrene isn’t as expensive as divinylbenzene, water softener systems featuring a higher crosslink are significantly more costly.
When resin features a lower amount of divinylbenzene, they often have larger beads. Those larger beads tend to swell up a lot more compared to their smaller counterparts. That swelling can make your water softener’s resin bed vulnerable to factors, including resin attrition and oxidative stress.
That means, if your water contains a high level of chlorine, you’ll benefit from choosing resin with a higher crosslink to help protect your resin bed from oxidation. However, if you select resin featuring a lower crosslink, that means it can hold more water. When resin can hold more water, that means it’s more effective at eliminating hard water issues.
When Should You Replace Your Resin?
As soon as you finish setting up your water softener, the recommendation is to replace the resin. The main reason is that the resin that comes with these units is typically low-quality. You might notice that standard water softeners work effectively without completing this step. However, using high-quality resin is the best option.
Typically, a higher quality water softener resin lasts for a decade or longer. Over time, iron and the resin’s organic coating are what causes it not to last. You can tell when it’s time to replace it according to the water’s hardness. For example, you might notice that your water’s softness is changing. If that’s the case, it’s time to replace it with a high-quality resin.
How Do You Replace it?
Replacing your water softener’s resin is a straightforward process involving the following simple steps:
- Make sure you turn off the water and unplug the system from the electrical outlet. Then, disconnect the control valves from the brine line, drain line, and water lines.
- Unscrew the control valve–this step might take more than one person.
- Remove the distributor tube and control valve by separating the two at the control valve.
- Remove the water and resin by dumping or pumping it out.
- If the inside of the tank looks dirty, use chlorine bleach to clean it out. You can use a toilet brush to scrub inside the tank.
- Use a funnel to pour the new resin into the tank.
- Put the distributor valve and control valve back on, screw the control valve back in, connect the control valve to the brine line, drain line, and water lines, plug the system back in and turn the water back on.
- Backwash the new resin for approximately ten minutes using the control valve.
- Put the control valve into the “normal service position.”
- Run water through faucets in your home for several minutes to flush the lines of air that might be trapped.

You might read many water softener resin reviews, but keep in mind that there are different resin types. The resin’s crosslink plays an integral role in your resin bed’s longevity and how efficiently it removes minerals. Once you understand these differences and each type of resin’s features and benefits, it’ll be easier to pick the best one for your water softener.
